Voice Controlled Search on Wireless Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile devices face challenges in accessing information efficiently due to small screens and numeric keypads, making text-based information retrieval systems like Google SMS slow and cumbersome for users.
Innovation Solution
A system and method that allows users to submit queries verbally using speech recognition on a wireless mobile device, converting the query to SMS format, transmitting it to a search engine, and receiving results in SMS format for display, with optional text-to-speech synthesis for voice output, and integrating advertisements processed by an intermediary server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If text-based information retrieval systems are used on mobile devices, then information can be accessed, but the small numeric keypads and screens make text input slow and cumbersome
Solution Approach 1:
The patent replaces the mechanical keyboard input system with a voice recognition system. Users speak their queries naturally instead of manually pressing numeric keys, converting speech to text automatically. This substitution eliminates the cumbersome text input process while maintaining information retrieval functionality, directly resolving the contradiction between ease of operation and productivity.
2Productivity
If voice recognition is implemented for query input, then text input speed improves, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary server that handles the complex voice recognition, query processing, and result formatting tasks. The mobile device itself remains relatively simple, acting mainly as a communication terminal. This intermediary approach allows the device to gain advanced voice-based query capabilities without significantly increasing its own complexity, as the heavy processing is offloaded to the server.
3Area of stationary object
If search results are displayed on the mobile device screen, then information is accessible, but the small screen limits the amount of information visible
Solution Approach 1:
The patent segments the search results into multiple text messages and sends them sequentially to the mobile device. Instead of attempting to display all results simultaneously on the small screen, the system divides the information into manageable chunks that can be received and displayed in a series of SMS messages. This segmentation allows comprehensive information delivery while accommodating the limited display area of mobile devices.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Provides a faster and more efficient way for users to access information without the need for manual text input, enhancing user experience by leveraging voice recognition and synthesis, and enabling monetization through advertisement integration.
Implementation Method 1
the mobile device prompts the user for additional information required to complete the query. The user is able to provide the needed information verbally using speech recognition software
Implementation Method 2
the mobile device uses text to speech synthesis to generate a voice speaking the received search results in addition to displaying them on the screen of the mobile device

AI summary
A method and system are provided by which a wireless mobile device (100) takes a vocally entered query and transmits it in a text message format over a wireless network (102) to a search engine (104); receives search results based on the query from the search engine over the wireless network; and displays the search results.
